1. It should be possible at some point to have an english translation as it is a communication business in a developped country... Also the change of subscription is hard to cancel where a wrong manipulation has been done and the refill did not work for me while 15 euros have been discounted for my bank account...Everything you might need around the mobile service can be found in the app.

2. In my case I have to contact the hotline for further information and changing my contract dataIt's a good guide & support for users to know the current standing of one's subscription & usage.

3. Toping up is also non-reliable, you end up easily toping up double the amount you meant to.The service is good , the network quality is also good, the app is good, they even give you sometimes a free bonus 15% discount or data.

4. No option for any other language but German, app is not as comprehensive (not as good overall) as similar apps - like the mobile Vikings one.

5. But this is quite shady practice to have random charges without notice.You can't see the costs of you current booked options, so you don't see how much money you need to top up to cover the expense of it as well (pre-paid options).

6. Very satisfied.First time a mobile provider app actually does something useful for me and doesn't bother me with cross selling ads all the time.

7. One star less for lack of the English version of the app.An only-for-german-reader app where it is not possible to copy/paste the text to get an English translation.

8. Top up and data top-up in specific is very weird: you cannot top up at any time your data runs out, you have to wait until a calendar month is off.

9. All in all, good Internet provider, app is more than functional and convenient.

10. Good Job guys!Good: Relatively smooth and easy to use.

11. My husband needs a new number (using Vodafone until today) and I introduced him a membership, for which I also get some kind of bonus.
